Compound Cabinet
Everything you take, in one cabinet.
Features
Every entry gets a grade.
A to D, based on how much human research there is. If the only evidence is a mouse study, it says so.
What interacts with what.
The app checks every pair in your stack, including any prescriptions you add. If nothing comes up, it says nothing's on record instead of giving you a green check.
Your stack, written down.
Check things off each day and jot down what you notice. A month in, you've got notes to look back on.
Here's what using it looks like.
Add what you take.
Find each one in the library and add it. Some prescriptions are in there too.
Read the evidence.
Each entry explains the research in plain English and grades how solid it is.
See what interacts.
Every pair in your stack gets checked, and each flag shows how serious it is and where it came from.
What it won't do.
None of these are coming in a later update.
Clear you to take something
If two things come back with no flag, there's no interaction on record. That's not the same as safe together, and the app tells you so on the screen.
Give you an AI to ask
There's no chatbot. Chatbots sound sure of themselves even when they're wrong, and there's already plenty of that on Reddit.
Interpret your labs
You can log a lab result and see where it falls in the range printed on your report. It won't tell you what the number means. That's your doctor's job.
Tell you what to take
Browse can point you to common starting points, or match goals you pick, and that's as far as it goes. It won't judge what's on your shelf. What you take is up to you.

“The bottle didn’t mention it.” Kieran Bishop on why he built Compound Cabinet.
“My pharmacy knew about my prescription and nothing else I was taking. The forums knew about everything I was taking and not much about how any of it worked. Nobody had the whole picture.”
- It won’t tell you what to take.
- It won’t sign off on anything either.
- If you check two things and nothing comes back, that means nothing’s on record, which isn’t the same as safe.

See what other people are taking.
Right now people swap stacks in group chats and Reddit threads, and none of it gets checked against anything. A later update brings that into the app, with the research sitting right next to it.
- Share your stack card. Look at other people's too. Cards list names and categories only, with no amounts and nothing about where to get anything.
- What people noticed, per compound. Journal notes people choose to share will build up into their own section on each compound's page, so you can see what other people experienced. It's labeled anecdotal and kept separate from the research. Nobody's running trials here, it's just how it went for them.

Common questions
Is this medical advice?
No. It's a reference. It doesn't diagnose, treat, or recommend anything. Ask your doctor or pharmacist before you change what you take.
What's in it?
193 compounds: supplements, nootropics, peptides, amino acids, adaptogens, and a set of common prescriptions. Each entry covers what it is, what the research says, how solid that research is, and who should avoid it.
How is the evidence graded?
Four grades. A is strong, B is moderate, C is limited, and D is anecdotal. The grade reflects how much human research there is. Research compounds that aren't approved for human use carry a notice saying so. A few of the studies the library cites:
- Creatine: Hoffman J et al. Int J Sport Nutr Exerc Metab. 2006. PMID 17136944
- L-theanine and caffeine: Owen GN et al. Nutr Neurosci. 2008. PMID 18681988
- Ashwagandha (sleep): Langade D et al. J Ethnopharmacol. 2021. PMID 32818573
- Lion's mane: Mori K et al. Phytother Res. 2009. PMID 18844328
Does it check my prescriptions?
Yes, for the medications in the library, and only the ones you add yourself. The app never pulls your medication list from anywhere. Most of the prescriptions in the library have few or no interaction records yet, so if nothing comes up, that only means nothing's on record. Ask your pharmacist too.
How much is it?
$8.99 a month or $69.99 a year, and the yearly plan starts with a 7-day free trial. There's no free version.
When does it launch?
Late 2026. Join the waitlist and you'll get one email the day it's out.
Is there an Android version?
Not yet. Android is planned for the first half of 2027.
What happens to my email?
It's saved with the date you signed up and which form you used, and it's only used for the launch email. It's never sold, and it's never shared with advertisers or data brokers. Use the unsubscribe link in that email, or write to support@compoundcabinet.com and it'll be deleted.
Know what you take.
On the App Store in late 2026.
